The meals, though unhealthy, seem to be big money-makers for the schools.

The school board is afraid that their banishment would cause a loss of revenue as students would go to nearby fast food joints to buy their lunch instead.

"What we saw based on those menus is that students simply will not choose the food," said Cathy Johnson, the district's associate superintendent, according to ABC Chicago.

The USDA's Smart Snacks in Schools offers $900,000 in federal subsidies if the school serves meals that are comprised mainly of "whole grain-rich" products, fruits/vegetables, or protein/dairy products. Additionally, entrees can only have 350 calories with set fat, sodium and sugar limits.

The Chicago Tribune reports that the school district will come up with its own healthy lunch menu options by working with a nutritionist.
